zabbix 4.2 的安装和设置（mysql57----centos7）

一、安装RPM

[root@localhost ~]# rpm -ivh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm

二、安装相关软件

[root@localhost ~]# yum install mysql-server httpd php -y

[root@localhost ~]# yum install zabbix-server-mysql zabbix-web-mysql -y

[root@localhost ~]# yum install zabbix-agent -y

三、创建数据库、导入zabbix需要的表、创建用户并授权

第一次启动mysql，会在日志文件中生成root用户的一个随机密码，使用下面命令查看该密码

[root@localhost ~]# grep 'temporary password' /var/log/mysqld.log

修改root用户密码

[root@localhost ~]# mysql -u root -p

Enter password:

mysql> alter user 'root'@'localhost' identified by 'p@$$w0rd';

创建数据库

mysql> create database zabbix;

导入zabbix需要的表

[root@localhost ~]# zcat /usr/share/doc/zabbix-server-mysql-4.2.3/create.sql.gz | mysql -uroot -p zabbix

创建用户并授权

mysql> create user zabbix@'localhost' identified by 'p@$$w0rd-zabbix';

mysql> grant all privileges on zabbix.* to zabbix@'localhost';

mysql> flush privileges;

四、编辑文件/etc/zabbix/zabbix_server.conf加入server信息

SocketDir=/var/run/zabbix

DBName=zabbix

DBUser=zabbix

DBPasswd=p@$$w0rd-zabbix

查看检查配置：

[root@localhost ~]# grep -v '^#' /etc/zabbix/zabbix_server.conf |grep -v '^$'

LogFile=/var/log/zabbix/zabbix_server.log

LogFileSize=0

PidFile=/var/run/zabbix/zabbix_server.pid

SocketDir=/var/run/zabbixs

DBName=zabbix

DBUser=zabbix

DBPassword=Zabbix-123456

SNMPTrapperFile=/var/log/snmptrap/snmptrap.log

Timeout=4

AlertScriptsPath=/usr/lib/zabbix/alertscripts

ExternalScripts=/usr/lib/zabbix/externalscripts

LogSlowQueries=3000

StatsAllowedIP=127.0.0.1

DBName=zabbix                            #zabbix所属数据库名称
DBUser=zabbix                            #zabbix所属数据库用户
DBPassword=www.xxxxxx.com                #zabbix数据库密码
StartPollers=30                        　#轮询的初始值（0-1000）
StartIPMIPollers=4                       #IPMI轮询的初始值（0-1000）
StartPollersUnreachable=30              # 轮询不可达的主机数（包括IPMI 0-1000）
StartTrappers=8                        　#捕获的初始值（0-1000）
StartPingers=4                          #ping的初始值（0-1000）
StartDiscoverers=0                      #自动发现的初始值（0-250）
CacheSize=384M                          #缓存大小
CacheUpdateFrequency=300                #缓存更新的频率
StartDBSyncers=8                        #数据库同步时间
TrendCacheSize=128M                     #总趋势缓存大小
AlertScriptsPath=/usr/bin               #脚本的存放位置
LogSlowQueries=1000                     #日志慢查询设定

五、修改时区：

vim /etc/httpd/conf.d/zabbix.conf

date.timezone = Asia/Shanghai

解决中文乱码

yum -y install wqy-microhei-fonts

cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/fonts/dejavu/DejaVuSans.ttf

六、设置开机启动

systemctl enable mysqld

systemctl enable zabbix-server

systemctl enable httpd
